Operation Error Messages
B-2 PN: 10580-00277 Rev. E Spectrum Master UG
RF Power applied to the input connector is too high. Remove or reduce the input power or add
additional attenuation. Sometimes out of band frequencies may be present that can cause an
Over Power Error. In highly rich RF environments it may be necessary to add an external
band pass filter to reduce unwanted interference. See the accessories section for a list of
available band pass filters from Anritsu. Out of band frequencies can often be detected by
increasing the Span to maximum in the peak detect mode of operation. Another resolution
may be to reset to factory defaults with either Factory Defaults, ESC+ON, or MASTER
RESET, System+ON. Caution: Use of MASTER RESET, System+ON, will erase all user
saved setups and measurement traces and return the unit to a fully Factory Default
condition. If the error persists, then contact your Anritsu Service Center.
Over Power Start FAILED
RF Power applied to the input connector is too high at turn on. See Over Power FAILED error
above.
Mixer Saturation: Increase Attenuation
or
Mixer Overdrive FAILED
Too much power applied with too little Attenuation. Increase attenuation. Sometimes even
out of band frequencies may be present that would cause a Mixer Overdrive Error. In highly
rich RF environments it may be necessary to add an external band pass filter to reduce
unwanted interference. See the accessories section for a list available band pass filters from
Anritsu. Out of band frequencies can often be detected by increasing the SPAN to maximum
in peak detect mode of operation. Another resolution may be to Reset to factory defaults with
either Factory Defaults, ESC+ON, or MASTER RESET, System+ON. Caution: Use of
MASTER RESET, System+ON, will erase all user saved setups and measurement traces and
return the unit to a fully Factory Default condition. If the error persists, then contact your
Anritsu Service Center.
B-3 Operation Error Messages
ADC Over range: Increase Reference Level
Input signal is too large for the Analog to Digital converter to process. Increase the internal or
external attenuation or, if using Auto attenuation, then increasing the Reference Level
should resolve the error. See also the “Mixer Overdrive FAILED” error (described previously)
for information on Out of Band RF power.
Calibrator Reading Error
Calibration reference source is not providing quality signal. Insure that the battery level is
adequate for operation or that temperature is within acceptable limits. Reset to factory
defaults with either Factory Defaults, ESC+ON, or MASTER RESET, System+ON.
Caution: Use of MASTER RESET, System+ON, will erase all user saved setups and
measurement traces and return the unit to a fully Factory Default condition. If the error
persists, then contact your Anritsu Service Center.
